Abstract
The utility model relates to a portal crane, which comprises two supporting legs and a main beam arranged on the upper part of the supporting legs, wherein a traveling trolley is arranged on the main beam; a small hook and a large hook are arranged on the traveling trolley; the lower part of the supporting legs is provided with a traveling driving device; and two ends of the main beam penetrate out of the upper parts of the supporting legs. Because the ends of the main beam penetrate out of the upper parts of the supporting legs, during operation, the traveling trolley can reciprocate between the two supporting legs and can reciprocate on the main beam outside the supporting legs, and the operating range of the portal crane is greatly widened.
Description
Technical field
The utility model relates to a kind of hoisting device, relates to a kind of transfer crane specifically.
Background technology
Weight-lifting equipment has obtained using widely in every field; Accomplish the transportation of personnel or various goods through weight-lifting equipment; Weight-lifting equipment is divided into transfer crane, crane in bridge type, beam crane and boom crane by device structure; Wherein transfer crane mainly representative equipment be gauntry crane, crane in bridge type mainly representative equipment is the bridge formation machine, boom crane mainly representative equipment is a tower crane.
Transfer crane is mainly used in work operations such as the up-down, parallel motion of building ground, factory floor and shipyard harbour weight, and the metal construction of transfer crane comprises two supporting legs as door-shaped frame; Supporting leg can be along track travel, and the top of supporting leg is provided with girder, and girder is provided with walking dolly; Walking dolly is provided with suspension hook; Present employed transfer crane, walking dolly can only be between two supporting legs crank motion, big limitations the operating range of transfer crane.
The utility model content
The problem that the utility model will solve is to above problem, provides a kind of operating range big transfer crane.
For addressing the above problem; The technical scheme that the utility model adopted is: a kind of transfer crane; Comprise two supporting legs and the girder that is arranged on supporting leg top, said girder is provided with walking dolly, and said walking dolly is provided with little hook and big hook; The bottom of said supporting leg is provided with travel driving unit, and the two ends of said girder pass from the top of supporting leg.
A kind of concrete prioritization scheme, the bottom of each supporting leg are provided with two travel driving units.
The utility model is taked above technical scheme; Have the following advantages: because the two ends of girder pass from the top of supporting leg; During work; Walking dolly both can be between two supporting legs crank motion, also can be on the exterior girder of supporting leg crank motion, increased the operating range of transfer crane greatly.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Description of drawings
Accompanying drawing 1 is the structural representation of a kind of transfer crane among the utility model embodiment;
The left view of accompanying drawing 2 accompanying drawings 1.
Among the figure:
The 1-travel driving unit; The 2-supporting leg; The 3-girder; The little hook of 4-; The 5-walking dolly; The big hook of 6-.
The specific embodiment
Embodiment: shown in accompanying drawing 1 and accompanying drawing 2; A kind of transfer crane comprises two supporting legs 2 and the girder 3 that is arranged on supporting leg 2 tops, and said girder 3 is provided with walking dolly 5; Said walking dolly 5 is provided with little hook 4 and big hook 6; The bottom of said supporting leg 2 is provided with travel driving unit 1, and the two ends of said girder 3 pass from the top of supporting leg 2, walking dolly 5 both can be between two supporting legs 2 crank motion; Also can be on the exterior girder 3 of supporting leg 2 crank motion, increased the operating range of transfer crane greatly.
The bottom of each supporting leg 2 is provided with two travel driving units 1, drives supporting leg 2 along the guide rail crank motion through travel driving unit 1, and travel driving unit adopts and gets final product with the employed travel driving unit of transfer crane at present.
